IMPROVEMENT m'PENouLuM cLooKs.

Specification forming part of Letters Patent No. 163,868, dated June 1, 1875 application filed October 19, 1874.

To all whom it may concern:

Be it known that I, VITALIS HIMMER, of New York, in the county of New York and State of New York, have invented a new and Improved Pendulum-Clock, of which the following is a specification:

Figures 1 and 2 are face views of my improved pendulum-clock, showing it in different positions. Fig. 3 is an edge view of the same. 7

Similar letters of reference indicate correspondin g parts in all the figures.

This invention has for its object so to construct a pendulum-clock that the same will be in proper running condition, even if not suspended or supported in the exact vertical position for which it may have been constructed.

The invention consists in pivoting the crutch-wire to the anchor, so that by the jointed connection the crutch-wire will be enabled to turn or swing independent of the anchor, which is necessary in order to prevent the pallets from entering too deeply into the escapement-wheel when the clock hangs inclined.

The invention also consists in providing the anchor with a projecting arm that moves between two fixed stop-pins on the frame of the clock, to define the motion of the anchor and prevent the pallets from entering too deeply between the teeth of the escapel'nent-wheel.

In the accompanying drawing, the letter A represents the escapement-wheel of a clock, and B the frame of such clock. 0 is the anchor, pivoted at a to the frame B, and provided with pallets b and d, which engage be tween the teeth of the escapement-wheel in the customary manner. D is the pendulum- .rod, and E the crutch-wire, which connects the anchor with the pendulum-rod. The pendulum-rod is hung tothe clock-frame in the customary or in suitable manner, and is embraced by or connected with the lower portion of the crutch-wire also in the customary or suitable manner. The upper end of the crutch-Wire is swiveled in the anchor, so that it can turn therein; or, if not swiveled in the anchor direct, or in a projection, 0, thereof, as shown, the crutch-wire is made jointed for similar effect. f is a projecting wire or arm, rigidly attached to the anchor, and g is a pin projecting from the frame B, above the wire f, while h is a pin projecting from the frame B below the wire f. These two pins 9 and h, by limiting the vibration of the arm f, limit, also, the movement of the anchor. Now, if the clock should hang or stand in proper vertical position, which is indicated in Fig. 1, and the pendulum should be vibrated properly, the motion of the pendulum would, by means of the crutch-wire, be transmitted to the anchor, and the anchor thereby caused to regulate the rotary motion of the escapement-wheel A in the requisite manner. The pins g and it meanwhile-that is, as long as the clock hangs straightwi11 hardly be necessary; but when the clock is hunginclined, as indicated in Fig. 2, the pendulum willhave a tendency to carry one pallet of the anchor deeper into the escapement-wheel than the other, which, of course, would defeat the entire object of the clock and cause it to stop running, and to prevent which the stoppins g and h are provided. if the clock is inclined to the right, as indicated in Fig. 2, the lower pin h will be struck by the projecting arm f of the anchor before the pendulum has completed its motion to the right, and, consequently, that part of the motion in the pendulum which takes place after the pin f has struck the stop h, will cause a similar motion of the clutch-wire E, independent of the anchor 0. Such independent motion of the crutch-Wire is permitted by having its upper end swiveled in the anchor, or by otherwise jointing the crutch-wire, and were it not for such joint in the clutch-wire, or in its connection with the anchor, the crutchwire would necessarily carry the right pallet 01 too deep into the escapement-wheel; or else, when the stop h is provided, the pendulum would be arrested in its motion to the rightbefore its normal vibration had been completed. When the clock is inclined too much to the other side, the pin 9 arrests the upward motion of the left-hand pallet b, and determines the position of the anchor, from which the clutch-wire is to begin its independent motion. As to the form of joint betweenthe crutchwire and the anchor, I prefer to screw it into a projection, c, of the anchor, as shown in the drawing, for the reason that the screw-thread on the end of the crutch-wire, though allow in g of the independent "ibration of the latter, 0, or a projection thereof, substantially as dowill still cause more friction than the pivot a scribed. of the anchor, which is necessary in order to 2. In combination with the anchor C and cause the crutch-wire to carry the anchor jointed crutch-wire E, the projecting pin f and through the normal operation of the clock; the stop'pins g and h, arranged substantially but any other suitable form of joint between as and for the purpose described. the crutch-wire and. the anchor, or in the crutch-wire itself, may be used.
